2. 1 What is new?

• The data transfer to Sunny Portal is now also possible when the inverter is directly connected to the PC.
- See chapter 12. 3 „Configuring Sunny Portal Mail” (page 129).

2. 2 Scope of Delivery

The program "Sunny Data Control" can be downloaded from www.SMA.de in the download area, or ordered as a CD: (SMA order number SMA-CDROM).
User Manual SDC-TEN080642 Page 11
Sunny Data Control SMA Technologie AG

2. 3 Scope of Application

Sunny Data Control is a PC program from SMA Technologie AG with which you can realize long-term storage of the data from your photovoltaic plant, and also visualize it. Sunny Data Control queries the data from your communication device (Sunny Boy Control and Sunny Beam) and saves it as Microsoft Excel files or CSV files on your PC.
With Sunny Data Control, for example, you can set up a complete overview of all inverter data (e.g.Pac, E-total, E-today) and display the inverter data in Excel in the form of charts. As an installer you can set the inverters' parameters, and you can send the data to Sunny Portal for visualization and storage. See www.SunnyPortal.com for more information on Sunny Portal.
With Sunny Data Control software version 3.81 and above, you can also connect an inverter directly to the PC. This connection is only permissible for the purpose of servicing, and may not be operated on a long-term basis.

PC Connection Possibilities
The following figure provides an overview of the connection possibilities from inverter to PC with Sunny Data Control. You can obtain further information at www.SMA.de, and in section 4 „Connecting the PC to an Inverter” (page 17).
It is only ever possible to have one type of connection between inverters, and to the communication device.
With an RS232 and USB connection, only one inverter can be connected to one communication device, or one inverter to one PC.

Safety Instructions SMA Technologie AG

3 Safety Instructions

Please follow all operating and safety instructions in this manual. Failure to follow these instructions could result in damage to the device and cause personal injury.
All work on the inverters may only be performed by qualified electricians! Follow all safety instructions contained in the inverter documentation!
With the Sunny Data Control program, your PV plant's safety-related inverter parameters can be changed. Such parameters may only be changed after consulting your energy supply company.
Operating Instructions
Data collected by Sunny Data Control regarding the power generated by your solar power plant can deviate from the electric meter. The Sunny Data Control data may not be used for billing purposes.
The PC, and thus Sunny Data Control, can be connected to the Internet via an ad­ditional router. Adequate security measures must be taken by using upstream hardware and software (firewall).

SMA Technologie AG Connecting the PC to an Inverter

4 Connecting the PC to an Inverter

A direct connection of a PC to the inverter is only intended for the purpose of servicing, and may not be operated on a long-term basis.
The direct connection is made via the SMA USB service interface with a 1.5 m cable and a USB interface for the PC connection (SMA order number: USBPBS)
For further information regarding this connection, please refer to the USB service interface's user manual.
Sunny Data Control supports the direct connection of an inverter to the PC with Sunny Data Control software version 3.81 and above.
Data Acquisition
How to gather and save data from an inverter connected directly to a PC is described in Chapter 11. 4 „Direct Data Acquisition from an Inverter” (page 102).

5. 1 Notes on the Use of Level Converters

Level inverters are devices which convert data from one signal type to another, for instance from RS485 to USB. With the aid of these level converters, a Sunny Boy Control / Plus or Sunny Boy Control Light can be connected to a PC which does not have the appropriate interface.
Compatibility with all level converters available on the market cannot be guaran­teed.
SMA provides the following level converters. These level converters have been tested, and function with the Sunny Boy Control / Plus and the Sunny Boy Control Light:
• RS232/RS485 to USB
- SMA order number: I-7561
• RS485 to RS232
- SMA order number: I-7520

5. 2 Sunny Boy Control / Plus

5.2. 1 Connection via RS232

RS232
RS232 communication characteristics:
• A maximum of one Sunny Boy Control / Plus can be connected to a PC.
• The PC must be equipped with an RS232 port. If it is not, please read section 5. 1 „Notes on the Use of Level Converters” (page 20).
• The Sunny Boy Control / Plus requires an RS232 Piggy-Back at the PC (COM 2) port.
Alternatively, the AUX (COM 3) port on the Sunny Boy Control Plus can be used if the port is equipped with an RS232 Piggy-Back.
• The maximum total cable length is 12 m
Cabling Recommendations
The connection between the Sunny Boy Control and the PC occurs by means of a commercially available null modem cable. Use the null modem cable provided.
If the length proves insufficient, use a commercially available null modem cable of the required length.
Jumper Functions at the Sunny Boy Control / Plus
With RS232 communication, no jumper must be mounted on the Sunny Boy Control / Plus at the PC (COM 2) port, or on the Sunny Boy Control Plus at the AUX (COM 3) port.

5.2. 2 Connection via RS485

RS485
RS485 communication characteristics:
• Up to 50 Sunny Boy Control / Plus devices can be connected to a PC.
• The PC must be equipped with an RS485 port. If it is not, please read section 5. 1 „Notes on the Use of Level Converters” (page 20).
• Each Sunny Boy Control requires an RS485 Piggy-Back at the PC (COM 2) port. Alternatively, at the Sunny Boy Control Plus, the AUX (COM 3) port can be used,
if this is equipped with an RS232 Piggy-Back.
• The maximum total cable length is 1200 m
Cabling Recommendations
The cable length and quality have an effect on the signal quality. To achieve a good quality signal, observe the following instructions regarding cabling:
• Use metallic D-Sub female connectors. Connectors made of plastic, or metallized plastic, can cause faulty data transfer.
• For the outdoors, use a communications cable with the following important qualities:
- Cross-section: at least 2 x 2 x 0,22 mm
-shielded
-Twisted Pair
- UV-resistant We recommend the following cable types for outdoors: SMA communications cable: COMCAB-OUTxxx* *available in the following lengths xxx = 100 m/200 m/500 m und 1000 m. Lappkabel: UNITRONIC Li2YCYv 2 x 2 x 0,22 mm
2
, and at least 2 x 2 x AWG 24
2
For the outdoors you can also use a data cable designed for indoor use, if you protect it against UV radiation with an appropriate cable duct.

Termination To increase the signal quality of the RS485 data bus, it must be terminated at both ends.
Each termination occurs with a 120 W resistor between the two data lines. Terminate the last Sunny Boy Control / Plus by means of a jumper. The position of the jumper is described in the user manual of the Sunny Boy Control / Plus.
Signal Biasing To increase the signal quality of the RS485 data bus, a maximum of one bias can be
connected in the data bus. We recommend connecting the bias at the PC.

Observe all safety instructions in the Sunny Boy Control / Plus documentation, and in the PC documentation.
Shut down the PC before you connect the Sunny Boy Control / Plus, as otherwise one or both COM ports may become damaged.
1. Plug the 9-pin D-Sub female con­nector into a free COM port on your PC. For the pin assignment of the RS485 connection, please re­fer to the PC's documentation, or the plug-in card's documentation. When connecting the cable, make sure that Data+ and Data- are a twisted pair. Shorten the wire of the fourth, unused conductor, so that short circuits cannot arise. Take note of the conductors' color cod­ing:
Data + ____________________
Data- ____________________
GND ____________________
2. If the PC is situated at one of the two ends of the RS485 data bus, terminate the end of the cable as described in the PC's documenta­tion, or in the plug-in card's docu­mentation.
3. Configure the RS485 data bus' bias as described in the PC's docu­mentation, or the plug-in card's documentation.
4. Lay the cable properly so that there is no risk of persons tripping over it.
